Definitions
- the present invention relates to a hydraulic membrane valve for the regulation of the flow of fluids, which has been perfected in certain structural aspects thereof, in order to achieve an optimum regulation of the flow of fluid that passes through it.
- the corresponding valve body contains a semiconic deflector element with its upper part determining an open flat face whose perimeter configures an isosceles triangle, the section thereof being approximately equivalent to that of the valve passage, according to its nominal diameter, due to that the passage of water through the valve is carried out inside such triangular section.
- the aerodynamic shape of the semiconic deflector favors the circulation of the fluid, both in the inlet zone and in the outlet zone, avoiding the production of turbulence in the flow and reducing pressure losses in the valve.
- the valve also includes a flat configuration membrane in its seating area, adapting to the sides of the outlet section in order to achieve the tightness of its partial or total enclosure.
- the elastic membrane itself adopts a hemisphere configuration or spherical cap that, to perform the closing function, sits on an area, in the shape of a circumference segment.
- the closing of the valve is carried out by introducing pressurized water into the chamber formed by the valve cover and the membrane itself ensuring the sealing of the enclosure, in some cases, by one or more springs arranged in said chamber, which compress the membrane against your seat, even when the fluid pressure drops.
- the valve is opened by draining the water contained in the chamber, which allows the membrane to deform, leaving the passage of fluid free.
- valve For use as a regulator, in a known process it is usually equipped with pilots (small hydraulic valves) that, by means of sensors that buy the pressure of the fluid at the outlet of the valve with that of the pilot setting, have the partial filling or emptying of the valve chamber, putting it in communication with the fluid inlet or discharge respectively, whereby the membrane adopts intermediate positions between those of total opening or closing.
- pilots small hydraulic valves
- the purpose of the invention that constitutes the object of this patent is the elimination of the problems of deficient regulation capacity of the known membrane hydraulic valves, described above, by means of an improved design of the closing mechanism, which optimizes its performance Hydraulic
- the valve body contains a semiconic deflector element, with its axis arranged longitudinally, whose upper part has an open flat face and whose perimeter forms an isosceles triangle of straight or mixed sides, the section of the latter being approximately equivalent to the of passage of the valve according to its nominal diameter, because the passage of water through the valve occurs inside the triangular section.
- the vertices of the semi-cone and the triangular opening are oriented towards the inlet part of the fluid to the valve.
- the aerodynamic shape of the semiconic deflector favors the circulation of the fluid, both in the inlet and in the outlet, avoiding the production of turbulence in the flow and reducing the pressure losses in the valve.
- the membrane adopts a flat shape in its seating area, adapting to the sides of the exit section to achieve the tightness of its partial enclosure or total; and it is preferably made with an elastomer sufficiently flexible to allow the continuous deformations that require its function, being able to incorporate internal reinforcements if deemed necessary by the service pressure of the valve.
- valve chamber when the valve chamber is completely drained, its complete opening takes place since the membrane deforms leaving the entire triangular section of passage, which is equivalent to that of the outlet pipe, of the nominal diameter free. from valvule.
- valve At an intermediate point in the regulation process, the valve will be partially open, the chamber partially filled with fluid and the deformed membrane with a double curvature profile.
- the inlet pressure is always higher than the outlet pressure for the fluid to circulate in the intended direction
- the pressure of the fluid contained in the chamber will be intermediate between the two, and will tend to apply the membrane against its seat, this effort being both
- the larger the acting surface, the greater the area of the membrane that will initially be applied against its seat will be that corresponding to the base of the triangular opening, and the passage section that will be free will be that corresponding to the vertex of said opening.
- the inlet pressure will tend to lift the membrane of your seat starting at the zone of least resistance, that is, at the apex of the triangular outlet section.
- valve in closing or reduction of flow will be the one of back to front, beginning by the greater flows; and conversely, in the process of opening or increasing flow.
- valve allows efficient operation as a regulator, in flow rates much wider than those of conventional valves, avoiding fluctuation problems of pressures they present.
- Figures 1 to 12 show a sequence in the process of opening the valve, from nothing to everything: from them,
- Figures 1, 2 and 3 correspond to the closed valve.
- Figures 4, 5 and 6 correspond to the slightly open valve, with a section through the vertex of the triangular outlet section.
- FIGS 7, 8 and 9 correspond to the valve giving way to an average flow.
- Figures 10, 11 and 12 correspond to the fully open valve, with the passage section equivalent to that of the outlet pipe.
- Figures 1, 4, 7 and 10 are longitudinal sections of the valve, by vertical vertical planes.
- Figures 2, 5, 8 and 11, are cross sections of the valve without cover by the planes whose traces are indicated respectively as AA ( Figure 1), BB ( Figure 4), CC ( Figure 7) and DD ( Figure 10) .
- Figures 3, 6, 9 and 12, are conventional plan views of the valve without cover, and with the membrane cut by the plane of its upper face.
- Its body (1) contains a semiconic deflector element (2), with its axis parallel to the longitudinal one of the valve, presenting at the top of said element (2) a flat open face (3) whose perimeter forms an isosceles triangle of section approximately equivalent to the passage of the valve according to its nominal diameter, to facilitate the circulation of the fluid when the valve is fully open, since the flow passes through the triangular section.
- the vertex of the half-cone (2) and therefore the extreme vertex of the triangular opening (3), are oriented towards the inlet part of the fluid to the valve.
- the elastic membrane (4) adopts a flat shape in its seating area, adapting to the sides of the triangular passage section to achieve the sealing of its partial or total enclosure, pressed against its seat by the fluid contained in the chamber formed by the cover (5) and the membrane (4).
- the opening of the valve is produced by draining the fluid from said chamber, with which the fluid inlet pressure pushes the membrane (4) away from its seat and facilitating its exit through the triangular passage section of the semiconic deflector (2) .
- the valve has holes in its body that serve as a connection for the use of pilots or other accessories. Said holes are located in the inlet (6) and outlet (7), as well as in the chamber (8). When the valve is used as an automatic regulator, these holes are properly connected to the pilot pilot.
